module Beaker::Shared::Semvar
Public Instance Methods
Gets the max semver version from a list of them @param [Array<String>] versions List of versions to get max from @param [String] default Default version if list is nil or empty
@note nil values will be skipped @note versions parameter will be copied so that the original
won't be tampered with
@return [String, nil] the max string out of the versions list or the
default value if the list is faulty, which can either be set or nil
